We have an HR34 in the living room and did have an HR20 in the bedroom, but the HR20 was getting a constant searching for signal. Tech came out and diagnosed the problem to be connections at the dish. He did replace other connections and also replaced the HR20 with an HR22. I didn't ask for it, he just said the 20 was old and we should replace now before it dies. That evening my wife noticed she can see the playlist of the HR34 and the 34 can see what she's recorded with the 22. Neither one of these dvrs has access to my wifi. The tech didn't ask for my wifi access code and I didn't realize he was setting up whole home. Without internet access how are the two dvrs communicating. Are they using the coaxial cabling to find each other? What other features of whole home can we use without internet? The ipad app? The HR34 doesn't have the doohickey for internet access. Based on the amount of disk space remaining display, it looks like the 22 records on its drive and the 34 on its drive. Is this true under whole home? Can the HR34 delete a recording from the 22 and vice versa?
